Hi,
tsbootrom-update is available at
ftp://ftp.embeddedarm.com/ts-arm-sbc/ts-7200-linux/binaries/ts-utils/tsbootrom-update
. You can put it on USB flash disk to use it from fastboot prompt.
You could probably try this version, it may be newer than that from sd card.
As long as you can boot from linux-2.4 sd card, you cant restore
original bootloader using tsbootrom-update:
mac=`ifconfig eth0 | grep HWaddr | cut -d' ' -f11`
tsbootrom-update -f -m $mac
Using TS-SDBOOT bootup i can boot 2.6 linux. I'll try to reproduce it
and post how to do it. Maybe try copying first 446 bytes from original
2.6 disk image - it's very easy to break masterboot:
dd if=<disk image file> of=<sd card device eg. /dev/sdb> bs=446 count=1
I am sorry for your trouble. It should be quite easy to get to
original state. I'ts very good idea to have ts-7440 at hand - you can
restore boot program when soething goes bad ...
